For active pharmaceutical ingredients (APIs), quality and regulatory compliance are insurmountable lifelines. Focusing on three major pharmaceutical-grade magnesium APIs—magnesium oxide, heavy magnesium carbonate, and magnesium sulfate—Messi Biology provides formulation enterprises with highly reliable magnesium salt API solutions, backed by compliance qualifications, stable product quality, and customized services.
Complete Compliance Qualifications to Lower the Threshold for Formulation Enterprise Filings
- Messi Biology holds a valid Drug Manufacturing License, with clearly defined production scopes for the three APIs.
- We possess GMP qualifications and have passed periodic GMP compliance inspections, ensuring our quality management system fully aligns with pharmaceutical manufacturing standards.
- Our three pharmaceutical-grade magnesium products hold official “National Medicine Zhunzi” approval numbers, and their CDE (Center for Drug Evaluation) registration status is “A.”
Exclusive Core Processes Exceeding Pharmacopeia Standards to Enable Import Substitution
- Utilizing an exclusive domestic metathesis reaction combined with deep impurity removal technology, we strictly control harmful impurities such as heavy metals, arsenical salts, and manganese salts. Our product specifications not only surpass the 2025 edition of the Chinese Pharmacopoeia (ChP) but also comply with European Pharmacopoeia (EP) and United States Pharmacopoeia (USP) standards, enabling successful import substitution.
- Our pharmaceutical-grade products boast a shelf life of up to 60 months with outstanding batch-to-batch stability, facilitating convenient storage and utilization for pharmaceutical companies.
Diverse Product Matrix Adapting to Various Formulation Processes
- Pharmaceutical-Grade Magnesium Oxide: Available in multiple grades, including standard, light, granular, low bulk density, active, and low-lead types. Standard magnesium oxide serves as a gastric antacid and tablet filler; light magnesium oxide is used in enteric-coated preparations to protect drug activity; granular magnesium oxide is tailored for multi-vitamin and mineral tablets; active magnesium oxide caters to oral liquid and injection formulations; and low-lead types precisely control trace elements like lead to meet rigorous formulation requirements.
- Heavy Magnesium Carbonate: A classic antacid API applied in various gastric tablets and granules, functioning to neutralize gastric acid and protect the gastric mucosa. We support customized particle sizes and distributions to adapt to different compression and granulation processes.
- Pharmaceutical-Grade Magnesium Sulfate: Divided into standard oral grade and low-iron/low-manganese injection-special grade. The injection grade strictly controls iron, manganese, aluminum, and bacterial endotoxins to meet the consistency evaluation requirements for injections; it is also applicable in laxatives, cholagogic preparations, culture media, and other scenarios.
- Additionally, we offer food-additive-grade magnesium salts for dietary supplements and food processing applications.
Customized R&D to Directly Address Individualized Pain Points of Formulation Enterprises
- Different formulations have distinct requirements for powder density, particle size, reactivity, crystal form, and impurity indicators. Rejecting a “one-size-fits-all” approach, we support tailor-made production.
- From sample proofing, small-scale trials, and pilot runs to mass production, our R&D and sales teams provide end-to-end follow-up, assisting clients with validation, on-site audits, stability studies, and actively facilitating the addition of new suppliers.
Pharmaceutical raw materials brook no negligence; every single bag of powder is closely tied to patient medication safety. Messi Biology continues to deeply cultivate the pharmaceutical magnesium salt sector, constantly iterating our purification processes. With compliant, high-purity, and customizable products, we work hand-in-hand with formulation enterprises to build a robust upstream raw material defense line for the healthcare industry.
